The UC3842A is a current mode PWM controller optimized for off-line and DC-DC converters. It features a low start-up current of less than 0.5mA and a trimmed oscillator discharge current of 8.3mA. The device includes automatic feedforward compensation, pulse-by-pulse current limiting, and enhanced load response characteristics. It also has undervoltage lockout with hysteresis and double pulse suppression, making it suitable for various applications such as switch mode power supplies, power modules, and industrial power supply units. The UC3842A operates at frequencies up to 500kHz and is available in multiple package options, including an 8-pin PDIP configuration.
